[Dismantling evaluation] light installation era 80CM SLR camera slide
Depth teardown for everyone today to evaluate a SLR camera slide —— Light Age SLR Camera Slide Length 80cm In this assessment, we used three sets of equipment with different weights and were installed on the same head. They were As a professional cameraman, a tripod and a tripod may be the most basic configuration. From a convenient and cost-effective point of view, this rail does not cost much, but it can meet most of the shooting needs. Simple and lightweight storage is its advantage Push the link To get the product is a large tray omitted Open the carton inside this canvas carrying case The boxing accessories include 1 slide body 2 slider 3+4 two brackets 5+6 two hex wrenches 7 Warranty Card Before the official installation we look at the details of the main components The straight slide housing has two stainless steel columns embedded in it. It serves as the core part of a slide rail, and the material workmanship is solid and reliable. Let's take a look, another core component, how the slider performance It comes with a fluorescent green bubble to determine the absolute level of the head In the absence of installation of both ends of the bracket, we can easily slide the slider out from either end to remove, from the appearance of the cutting process is very fine, no glitches, lamenting the maturity of CNC technology, more and more to Domestic products bring higher cost performance Since it was dismantled, it was all dismantled. With the gift of a hex wrench to open the four screws on the top cover, there is no difficult place, it is so direct, if compared to the Apple phone to replace the battery, it is simply a violent demolition Open the following picture At a glance, four screws, one axis screw are used to fix the head, and one pulley assembly (which is the right block with four wheels of black aluminum) we mainly understand his role There are two inner hexagonal top wires on his side Looking at the past from the front of the sauce, there are only two adjustment wheels on the four wheels. Why is this? Because you only need to adjust the position of two of the pulleys, you can make the slider get a reasonable clearance inside the slide rail (which can not only make the slider slide freely, but it will not be able to move at a constant speed because of too much resistance). Plug in the matching hex wrench, we can start to adjust the position of two of the pulleys, and here we recommend that you reinstall the pulley block to the slide, while adjusting, sliding, until you get a satisfactory feel, and then replace the top cover, (new The slider is a little bit sloppy when the rails are in hand. As long as you are careful, you will get a perfect experience because everything is too simple. ============================================ After talking about the main body, let's look at the brackets on both sides Whether the slide is stable or not depends on the bracket to check it off. How about the craft of the bracket? They can come in almost any angle, but if used with a heavy machine, I suggest to hit the maximum angle, because they only have this one angle is limited by the control of the bundle. Of course, if the equipment used is a mobile phone or a micro-micro bill, it can be adjusted to any angle with confidence. Another point is its rubber ball cushion The adjustment method can be seen very intuitively, the structure is very simple and easy to understand, the screw out heightening, tightening and lowering, the blue aluminum ring is used to control the sliding ================================= In the following we will take a look at his combined form (finished body) The inside of the bracket has a reserved groove just enough to insert the track By tightening the hexagonal jacking wire at the bottom of the bracket, we complete the fixing work and the rails are assembled. The first is the lightest iphone6s 0.3 kg The pan tilt is very smooth, and it feels perfect for 10,000 slides. I don't feel any vibration from the gap between the roller bearing and the slide rail. Because of the light weight of the device, we started to adjust the slider and if the adjustment was too tight, it would feel somewhat slippery, and a slightly looser adjustment may result in a better sliding experience. ================================================== ============ Next we use the Nikon D800 and 14-24 kit. Its weight is about 2 kg. The performance of the chute is still good, and after several smooth pushes, the device that feels this weight appears to be the developer's design standard. Because we rarely feel the sense of damping caused by the clearance of the slide rails, such load-bearing capacity is also the device combination used by most video teams in this era. (For example, the various combinations of Canon 5d3 and SLR lenses have almost the same weight. Between 2 kg or so). With PTZ's own tilt function and rotation function, we can take a perfect motion picture that is similar to professional equipment. It is recommended that there are users or video enthusiasts who want to purchase this slide rail. As long as your equipment does not exceed this weight, this slide is undoubtedly the price-performance option, and the slideway in the light-weight era has a weight of only 2.2. Kg, very portable, just take a foot back and put it in your own canvas bag. Compared to the design of a certain rail in South Korea, it is a cumbersome design ================================================== ======== Finally, we chose a set of quasi-professional video equipment weighing up to 4.3 kilograms (and this last experiment is also an experiment that I think should be called “destructive experimentationâ€). After all, it is to see what happens to the slides under extreme conditions. Therefore, it is not recommended for ordinary users to do such a test. In case of a fall of the machine, it is not responsible for the damage to the slides. After installing the machine, it is slightly top-heavy from the intuitive experience, because the body weight is more than twice the weight of the rails. However, when the left and right pushes, the slides are still smooth and there is no uncomfortable place. This will inevitably surprise people. We then performed several unusual lateral forces to see how the slides responded to the force response in the cross-sectional direction. Results Here, it was observed that the slider under the pan tilt was only slightly twisted, but no major abnormalities occurred and the body quickly returned to stability. Having done this experiment, I think there are still some limits, I think it's time to show real technology! ! ! We fought to move the slides and equipment to the trunk of the car to take a "off-road" challenge! ! ! Saying that in order to measure I also fight the life of equipment. The equipment was placed in the trunk for a full 30 kilometers. The 30 kilometers were mainly urban roads. There was acceleration and braking. There were well covers for sewage wells. There was also an underground garage downhill and downhill, but it wasn't really going off-road. It. At the end of the journey, remove the slides and the machine and check it. As a result, the slider and pan/tilt head are still stable, and the machine is all in good condition. However, there is some instability between the slider and the track. The specific indication is that the hand is slightly forced laterally on the pan tilt and a gap can be felt. However, we mentioned before how to adjust the pulley clearance under the slider, take out the hex wrench that comes with it. After a simple adjustment, the slide is rejuvenated, as if nothing had happened. This kind of load experiment I think has far beyond the actual use of the slide scene, so there is a need for inspectors I think the time does not need to increase, and now there are many similar products on the market, used in the selection of equipment time The cost should not be too high. If the time for selecting the chute is more than 24 hours, then I have to say that this day is spent. Compared to foreign big names, I have to say that there are still gaps in this product, but I have to say that compared to the price, it is good to be born in China. What do you mean? I tell you, come up with a mobile phone to unlock, go to Jingdong app, search for light rails. The price is so high to buy a one and you will know it. The professional classmates must have understood that it is a reserved hole for installing the PTZ quick-fit board. Of course, these holes can also be screwed directly to a tripod or a lighthouse without a pan-tilt. When not mounted on the pan-tilt, a relatively stable shooting platform can be obtained, but the X-axis is lost. Angle adjustment and the level of convenience of the ball bowl head. The use of rails, see it, a flexible product, as long as he reserved enough interfaces, to give users a wireless space reserved To sum up, is it not necessary? Cost-effective choice, a small cost must shoot. Suitable for equipment with a total weight of up to 3 kg. The included wrench can be escorted at all times (small pockets in the canvas bag). Simple storage, overall flexibility, portability, quick assembly.
